DROP-WINDOW.

To all whom it may concern:

Be it known that I, HERMAN C. MAISE, a citizen of the United States, aresident of the city of Detroit, county of Wayne, State of Michigan,have invented an Improvement in Drop-Windows, of which the following isa specification.

y invention relates to sliding or drop windows, particularly vehiclewindows, although it may be advantageously employed in connection withwindows of buildings and the like, and has peculiar utility inconnection with windows adapted to close an irregular opening, such asis formed when one of the window stiles is vertical and the otherinclined.

Such a condition is encountered in the front side windows used onautomobiles at the present time, these windows having an irregularopening formed by a vertical stile erected at therear of the front door,or elsewhere upon the body, and an inclined stile, in line with, orforming one of the wind-shield supports.

So far as I know, up to the present time it has been impossible toarrange such a window having an inclined edge, so that it may bepartially dropped, because of the fact that when the window is loweredto any appreciable extent, it is, by reason of its inclined edge,narrower at the Window opening, and lateral movement of the window outof its guides takes place. The practice at the present time hastherefore been to either make these irregular shaped windows in part orin whole stationary or to provide only two positioITs of the windowz'.6. one fully raised and one fully dropped, or entirely removed.

My invention has for its Ob ects to provide a window of irregular shapewith guiding and holding means, so that it may be lowered to any desiredextent and that at the same time lateral movement thereof will beprevented. Such guiding and holding means are also designed to cushionthe w1ndow, and thereby prevent breakage thereof and to guide the windowin the vertical direction. Window operating means are also provided,whereby the window may be raised and any binding of the window andguides will be prevented.

In the drawings forming a part of this specification, I have shown myinvention applied to a Springfield type body, but it Specification ofLetters Patent.

Patented Jan. 1, 1918.

Application filed February 28, 1917. Serial No. 151,390.

should be understood that these drawings and this specification describeonly a specific example of an embodiment of my inven tion, which I havefound to be useful and operative, and that I do not intend to con finemyself to the particular details illustrated and described, since itwill be evidentto those skilled in the art that many modifications andchanges may be made, without departing from the spirit of my invention.

Figure 1 is a side view, taken from the inside of an automobile body,showing a window embodying my improvements; F ig. 2 is a horizontalsectional view of my improved window; Fig. 3 is a detailed sectionalview of the vertical stile of my improved window.

The drawings, illustrate the application of my invention to the nowwidely used sashless type of window, provided with a tubular metallicframe, such as used on the Springfield type bodies at the present time,but it should be understood that my invention is not confined to thistype of window, and is capable of use in connection with windows havingwooden or'metallic sashes and in connection with other forms of windowframe.

Referring to the drawings, the window 1, is adapted to close the openingformed between the vertical stile 2 and the inclined stile 3 and to bedropped into a recess formed in the door 4. Stiles 2 and 3 may be hingedas at 5, so as to fold down in the manner common in Springfield typebodies.

The stiles 2 and 3 are preferably formed of metal, the stile 2comprising a channel portion having in-turned lips 6. The channelportion and lip 6 engage an enlarged edge member or protecting member 7which may be attached along the entire edge of the glass 1, whichcooperates with the vertical stile 2. If desired, however, this enlargedmember may not extend throughout the entire length of the vertical edgeof the glass, and may consist of one or more relatively short enlargedportions. The edge member 7, may be conveniently formed of a padding offelt or other suitable material 8,, surrounded by a fabric cover 9, thewhole being held in place upon the edge of the window by means of ametallic channel 10. Member 7 thus forms a cushion between the glass andthe window guide,

and owing to the factthat it is thicker than the distance between theinner ends of the inwardly projecting 'lips 6, lateral movement of thewindow is prevented.

The inclined stile 3 may be conveniently formed of a metallic channel 11inclosing a felt or other protective padding 12, held in place bychannel 11 and any other suitable means if desired, such as screws 13.

In order to prevent binding of the window in the guides, I attach thepull strap or other window operating means 14 to the lower edge of theglass 1, at a point between the vertical center line thereof, and itsinclined edge, thus, when the window is raised there is a tendency tothrow the glass to the left, as shown in Fig. 1, thus preventing theupper left hand corner of the glass 1 from bearing against the inside ofthe lips of the channel formed in stile 2. Thus offsetting the windowoperating means from the center of the window also prevents any slightsagging or lateral 'movement of the window, which might produce abinding action between the lower right hand corner of the window and aguide which. may be formed in the door recess as at the point 15.

If desired, the window may be slightly elongated as indicated by thebroken line 16 in Fig. 1, to produce a portion having vertical paralleledges to engage guides formed in the door recess. The lower edge of theglass may be provided with any suitable means for holding the glass inits elevated position, such as the usual channel and fence, and anydesired means may be applied in any intermediate position.

What I claim is:

1. A drop window for vehicles, comprising a frame, including onevertical and one inclined stile, a sheet of glass adapted to close theopening between said stiles and means attached to the vertical edge ofthe window and cooperating with the vertical stile to preventlongitudinal movement of the window.

2. A drop window for vehicles, comprising a frame, including onevertical and one inclined stile, a sheet of glass adapted to close theopening between said stiles, an enlarged edge member carried by thevertical edge of the glass and means carried by the vertical stile forengaging the edge member to prevent movement of the glass, when lowered,toward the inclined stile.

In testimony whereof, I have signed my name to this specification.

HERMAN C. MAISE.
